What Are The Main Similarities And Differences Between DNA And RNA?

The chemical structure of RNA is very similar to that of DNA, but differs in three primary ways:

DNA

RNA

Double-stranded

Single-stranded. By, complementary base pairing can form intra-strand (i.e., single-strand) double helixes, as in tRNA.

Longer chain of nucleotides

shorter chain of nucleotides

Sugar is deoxyribose

More stable

The hydroxyl groups in the ribose backbone make RNA less stable

Complementary base pair of adenine is -thymine

– is uracil
